But that's not important. What's important is what happened just now.

Wu Liang quickly checked everything around him and did not find any unusual figures. There were not many places to hide in this area, and if there was anything, it would not be easy to avoid the sight of the Hu army.

Besides.

Even if something sets fire...

Wu Liang walked closer to the source of the fire, and after careful inspection, he felt more and more incredible.

Because the dwarf trees in this area are all alive and there is not a lot of flammable dry grass around, even if there is something to prevent fire, it will take a lot of effort to light a fire.

But at this moment, the burning trees in the middle have been burned into charcoal that is falling off, and it is obvious that they have just completed the most complete combustion.

This is obviously unreasonable.

At least in Wu Liang's consciousness, any conventional method of making fire would never be able to burn a living tree to such an extent in such a short period of time. If he had to use one word to describe the situation at hand, Wu

Liang felt that he could only choose "destroying the dead", which was completely "destroying the dead" at the physical level.

besides.

What happened to the lights and loud noises before?

Wu Liang was puzzled.

Everyone in the Hu army remained silent, with looks of surprise and suspicion on their faces.

Wu Liang, a time traveler from later generations, could not explain the situation in front of them. Naturally, it was difficult for them to come up with a reasonable explanation. If they continued to think about it, they could only analyze it in the direction of ghosts and gods.

"Sir, this fire is very strange. What can you tell?"

In the end, Yu Ji couldn't help but stepped forward and raised the questions in his mind on behalf of everyone.

"..."

Wu Liang shook his head helplessly, and then said to Yang Wanli, "Yang Wanli, you first dig out an isolation zone with the fire to prevent the fire from spreading uncontrollably and affecting our operation this time."

"Isolation zone?"

Yang Wanli and everyone looked suspicious. They really didn't know what the isolation zone was.

"It means digging a gully around the perimeter of the fire area. It doesn't need to be too deep. Just remove all the trees and weeds connected to the fire source. Then the fire will burn out when there is no combustible material in the gully."

Wu Liang explained patiently.

"I understand, brothers, follow me!"

Yang Wanli suddenly realized it and immediately led his people to follow the instructions.

Wu Liangze was still observing the surrounding environment, and when he compared the fire scene in front of him with the scorched earth he had passed before, a question suddenly emerged in his mind, and then he said to everyone: "This small world has at least existed for a long time.

Hundreds of thousands of years, and may even be directly related to the miracle doctor Bian Que during the Yellow Emperor's period, but looking around, there is not even a big tree that is more than a hundred years old... Not to mention a hundred years, it is a tree that has lived for dozens of years.

We haven't seen 20-year-old trees yet, and the dwarf trees in front of us look like saplings that have only been growing for a few years at most. This is already a strange thing, what do you think?"

"Hiss... When the young master said this, I immediately felt strange."

Yu Ji frowned and nodded repeatedly, "Besides, this place is completely uninhabited. Even if someone luckily walks in, 80% of them will be turned into bones everywhere, let alone what is done here, so there should be no human factors."

"Does Brother Youcai mean that this inexplicable fire may be the cause of this situation?"

Zhuge Liang's mind became more vivid, and he immediately understood what Wu Liang meant, and said, "Think about the scorched earth we passed before, a similar fire must have occurred, and judging from the situation at the scene, the time when the fire occurred

The distance shouldn't be long now... If there is a fire in this place every now and then like now, these trees will be like weeds. They will be burned and grow again. If the cycle repeats, they will never grow into towering trees.

Talented brother, am I right?"

"Well, I do have such a guess."

Wu Liang nodded slightly.

While listening to everyone's analysis, Cao Ni asked questions again and again: "But what is the cause of the fire? Is it directly related to the sudden light and loud noise just now? That inexplicable light and loud noise

What is it again?”

"..."

Everyone fell into silence again.

This was the problem that Wu Liang was unable to solve for the time being. Yu Ji had already understood in his mind that he had calmed down a little before and did not get a positive response from Wu Liang. Therefore, neither Yu Ji nor Zhuge Liang continued to ask further questions at this moment.

Cao Ni obviously didn't have such emotional intelligence yet, and asked curiously: "Why don't you speak? Gentleman, why don't you speak?"

"Because I don't know either."

Wu Liang smiled and said, "But the light and loud noise are probably not trivial. Everyone needs to be more cautious next time. Even if you notice something strange, you must report it to me immediately to avoid making a big mistake."

…

After Yang Wanli and others dug out a simple isolation zone, the fire was slightly smaller. However, because all the living trees were burning, the smoke rising at this moment was much larger than before.

Wu Liang conducted a more detailed exploration in the area.

Unfortunately, the results of the investigation were not optimistic, or it could be said that they yielded nothing. Not even a trace of anomalies worthy of in-depth study were found.

In the end, Wu Liang had no choice but to put the matter aside for the time being and continue his exploration of the "Fairy Mountain" itself.

Soon after.

Everyone returned to the vicinity of the three gate towers.

Wu Liang decided to start from the foot of the "Fairy Mountain" facing the three gate towers. Analyzing from normal architectural logic, if there is a hidden underground palace or cave here, then 80% of the entrance should be facing the three gate towers.

.

However, after some exploration at the foot of the mountain here, nothing was found.

In this case, I'm afraid we can only search the mountain slowly.

Fortunately, with these three gates, Wu Liang is almost certain that this place definitely contains a shocking secret, so there is no need to worry about finding nothing in the end.

"Let's find a place to camp first."

With this idea in mind, Wu Liang was ready to fight a protracted war, so he said to everyone, "Let's set up the camp next to the creek where we used to get water. Not only is it convenient to get water, but it also has a better view.

It’s open, so if there’s any disturbance, we’ll be able to detect it right away.”

So everyone quickly gathered together and headed to the creek south of the "Fairy Mountain".

During this process.

The Hu army has still not seen the kind of weirdo that Daquan mentioned before, and has not encountered any life-threatening danger for the time being. Under such circumstances, some people have gradually begun to wonder where the numerous bones in this small world came from.

Coming.

If we only look at those bones, this small world should be a forbidden place of death, right?

However, it has been several hours since the Hu army entered this small world, and except for the previous fire, they have not received any death threats at all.

"Sir, this place is completely different from what I imagined. Do you think it's possible that some things have changed since this place became the mouth of the Yellow River?"

While the soldiers of the Hu army were setting up camp, Yu Ji quietly called Wu Liang to the side and whispered worriedly, "If this is the case, will it have an impact on what we are looking for on this trip?"

What Yu Ji said was naturally the solution to the strange poison. Various previous signs showed that "Bian Que" was closely related to the strange poison in their bodies. Although Yu Ji has lived for more than ninety years, he is more poisonous than anyone else.

Cherish life.

However, this concern is actually not unreasonable.

After all, the Yellow River has now flooded most of the surrounding areas. If the entrance or cave of this "fairy mountain" has been completely flooded by the Yellow River, then even if they searched the entire "fairy mountain", it is absolutely impossible to find anything.

harvested.

"I think this is unlikely."

Wu Liang pondered for a moment, and then said to Yu Jikuan, "This place is close to the sea, so even if there is a secret cave or underground palace, it is absolutely impossible to build it at a low place, otherwise it will be penetrated by sea water, and the water of the Yellow River reaches here

It is almost the same as the sea level. If the Yellow River can have an impact here, then the sea water should have changed this place in advance, and it will not be the Yellow River's turn."

This is indeed the case. When later generations built public rail transit in coastal areas, they rarely dug subways out of the ground. Instead, they chose to build bridges and build light rail in the sky. This is actually the same reason.

"I hope so."

Yu Ji still said worriedly.

Just like when I said this.

"Sir, look what that is!"

The soldiers of the Hu army who were camping not far away suddenly shouted.

"?!"

Wu Liang immediately looked back.

I saw a white ball of light floating about one meter above the ground on the other side of the stream!

This ball of light is about the size of a football, in an irregular oval shape, and very bright. It looks like a street lamp suspended in the air.

"Hiss!"

At the same time, Wu Liang heard such a slight noise in his ears, as if a wild beast was humming.

"this……"
